There probably is no power steering fluid in the 05 Saturn. Saturn employs an electric assisted power steering system that still has a rack and pinion, but is electrically operated. A much easier, more bulletproof design in my opinion.
There is not much difference between power steering and transmission fluid. Many people use power steering in place of transmission fluid because it is cheaper.
It depends on how much of it you have.
I paid $ 129.99 at the GM dealership for power steering flush & fill with synthetic fluid.
there should be a line where you pour the power steering fluid telling you when to stop. if there isn't it should say in your car manual.
Use a turkey baster to remove excess fluid
yes because brake fluid wont wear out as much No, brake fluid will destroy the seals in the power steering system.
usually about 4 pints
Probably about $3.00/pt.
not too much of a car buff, but I do know that the power steering pump is on the left side of the engine, right next to or under the pully system for the fan belt. power steering fluid is clear. It could be your power steering pump, or a bad seal on a hose causing it to leak.
All brands of steering fluid are pretty much made the same. Check your automobile's manual to see if there is a certain type of steering fluid that can only be used. If not, then the brand does not matter.
There are multiple methods to purging power steering systems of old fluid. In this application one do it yourself method requires the use of a turkey baster and container for used fluid. Using the baster old fluid can be sucked out of the power steering reservoir. Once emptied it can be filled with fresh fluid. Doing this procedure will extract much but not all of the old fluid. Another option is disconnecting all the lines and letting the system drain, and then recharging.
